I am concerned about an apparent misencoding for ioctl KVM_SET_IRQCHIP kvm/include/linux/kvm.h defines KVM_SET_IRQCHIP as #define KVM_SET_IRQCHIP _IOR(KVMIO, 0x63, struct kvm_irqchip) But the verb "SET" in the ioctl name would imply that the ioctl encoding constructor should be _IOW, not _IOR. Note also that KVM_SET_PIT seems to have the same encoding issue.
Yes, there are some bad encodings for the kvm ioctls. Unfortunately Linux doesn't enforce the directions, so it wasn't discovered in time.
